Applieation filed Octoher'h, 1 839 To (LZZ whom it may concern:

Be it. known that 1, Lines 0. Burns, a

citizen of the United States, residing at East Orange, Essex county, New Jersey, have invented certain new and useful improvements pressible packing, by which packingthe flange or hub and spigot fixtures.

may beeffectively held andeoupled to similar pipe ends or otheriittings, as elbows, rs,

The invention furnishes. aineans of uniting any pipe-flanges, and where thin sheetmetal pipe is to-be coupled it requires the bending of the pipe at its "end intoaproject- ,ing flange integral with tnepipe'."

' The invention consists in the combination, with the pipe-flange, of a yielding packing applied as a gasket to the face of the flange and bent over theriin of the flange and'down upon its inner or rear side, and suitable clam p ing devices to press upon the outside of such packing to clamp the flange within it.

. It also consists in certain modifications hereinafter described and claimed.

.Wheretheends of twopipes are to be united, the lead gasket would be provided with cirin Pipe-Couplings with Lead Joints, fully decumferential rings upon opposite sides' and' clamping'plates would be applied to'the pipes behind the flanges and provided with'annularrecesses to inclose the lead gasket and clamp the pipe ends. together; but Wherea single pipe end is clamped to an adjacent fit ting the gasket would b'eprovided with an annular ring at one side only and the opposed fitting may be constructed with a fiat face to press the'gasket against the pipe-flange and form a joint therewith.

The construction is fully shoivn in the annexed drawings, invvhichv Figure l'represents a section of two pipe ends with the gasket and coupling-plates in position thereon ready for the making of the joint. Fig. 2 represents the pipe ends coupled together'by the gasket and plates. Fig. Sis.
